1. Hybrid & Gasoline Power Transmission
As a core component for Toyota/Lexus hybrid and gasoline models, the U760E transfers power via two modes:
Gasoline Mode: Transfers engine power to drive wheels through the torque converter and planetary gear sets, with torque multiplication (2.8-3.5x) for strong acceleration.
Hybrid Mode: Coordinates with the electric motor via a hybrid coupling module, distributing power from both engine and motor to optimize efficiency. During regenerative braking, it reverses power flow to recharge the hybrid battery.
2. Adaptive Hybrid-Gasoline Shifting Modes
Working with the vehicle’s TCU, the U760E supports four adaptive shifting modes:
Eco Mode: Upshifts early (1,800-2,300 RPM) for maximum fuel/electric efficiency, ideal for urban commuting.
Normal Mode: Balances performance and efficiency, shifting at 2,400-3,000 RPM for daily driving.
Sport Mode: Delays upshifts to 3,600-4,600 RPM, enhancing throttle response for dynamic driving.
EV Priority Mode (Hybrid Only): Prioritizes electric power, using the gearbox to maintain low-speed EV operation.
The TCU learns driver habits and hybrid battery status, adjusting shift timing to optimize performance and battery life.
3. Hybrid-Optimized Torque Converter Operation
The hybrid-specific torque converter activates its lockup clutch at 40-50 km/h (5 km/h earlier than the U660E) to eliminate slippage, improving efficiency by 12-14%. During hybrid mode, it coordinates with the electric motor to smooth torque transitions, reducing vibration during mode switching. A enhanced torque damper absorbs engine and motor vibrations, enhancing ride comfort.
4. Precision Electronic-Hydraulic Control
The integrated electronic-hydraulic valve body directs fluid flow to actuate clutch packs and hybrid coupling components. A digital pressure regulator maintains pressure within 0.9-3.5 bar (±0.04 bar accuracy) to handle variable hybrid torque loads. A 6μm ultra-fine filter traps debris from engine and motor operation, protecting internal components and extending service life.
5. Hybrid TCU Communication & Diagnostics
The U760E connects to the TCU via a 20-pin connector, transmitting real-time data: fluid temperature, pressure, gear position, solenoid status, torque converter lockup state, and hybrid coupling status. For faults (e.g., hybrid clutch failure, solenoid malfunction), it stores DTCs such as P0793 (pressure control solenoid C malfunction) and triggers multi-level warnings. Mechanics use Toyota Techstream or Lexus Diagnostic System to retrieve codes, calibrate hybrid modes, and perform system resets.
6. Comprehensive Safety & Hybrid Protection
Park (P) Position: A hardened parking pawl (HRC 60) with dual-locking mechanism prevents rollaway, even under hybrid torque loads.
Reverse (R) Interlock: Requires brake pedal depression and vehicle speed ≤5 km/h, plus hybrid motor shutdown, to prevent accidental shifts.
Limp-Home Mode: Limits to 3rd gear (gasoline) or 2nd gear (hybrid) to protect the transmission and hybrid system.
Overheat & Hybrid Protection: Activates at 140°C fluid temperature or abnormal battery status, reducing engine power and switching to safe hybrid mode to prevent damage.
1. Expanded OE Compatibility for Toyota/Lexus Mid-to-High-End Models
Building on the U660E’s compatibility, the U760E Gearbox Assembly is an upgraded 6-speed automatic transmission designed for a broader range of Toyota and Lexus mid-to-high-end vehicles. It is fully compatible with Toyota Avalon (2013-present), Camry Hybrid (2012-2022), Highlander (2014-2023), as well as Lexus ES 300h (2013-2022), RX 450h (2016-2023), and NX 300h (2015-2021) — covering both gasoline and hybrid powertrains (2.5L hybrid, 3.5L V6 gasoline). Adhering to Toyota’s updated OE standards, it matches critical parameters: variable bell housing flanges for hybrid/gasoline engine interfaces, 24-spline input shaft, 28-spline output shaft, and 20-pin TCU communication protocol with ±0.05mm tolerance. This expanded compatibility supports both conventional and electrified powertrains, making it a versatile choice for repair shops servicing premium Toyota/Lexus lineups.
2. Advanced Hybrid-Compatible Technology & Proven Reliability
The U760E integrates Toyota’s hybrid-specific transmission technology, featuring a reinforced mechanical structure and optimized electronic-hydraulic control system tailored for hybrid powertrain demands. With over 12 years of market validation, it significantly reduces failure risks associated with hybrid mode switching. Core components are engineered for durability: hybrid-adapted planetary gear sets, corrosion-resistant valve bodies, and torque converters with enhanced lockup clutch materials. Real-world data confirms that properly maintained U760E gearboxes achieve a service life of over 250,000 kilometers, outperforming many hybrid transmission alternatives.
3. Robust Hybrid-Optimized Construction
Gear System: Core gears and planetary sets are crafted from 20CrNi2Mo alloy steel, processed via vacuum carburizing (depth: 1.5-1.8mm) and precision honing to reach HRC 60-63 surface hardness. This enables the gearbox to withstand continuous torque loads of up to 380 Nm, matching the combined output of Toyota’s 3.5L V6 and hybrid electric motors.
Torque Converter: Equipped with a hybrid-specific torque converter featuring a triple-impeller design and low-friction lockup clutch, reducing slippage by 15% compared to the U660E and improving power transfer efficiency in hybrid mode.
Housing & Hydraulics: The die-cast ADC12 aluminum alloy housing includes integrated heat sinks for hybrid system thermal management. The hydraulic system uses a variable-displacement pump and high-response solenoids to adapt to fluctuating torque from hybrid powertrains.
4. Enhanced Shift Smoothness & Hybrid Fuel Efficiency
Calibrated for both gasoline and hybrid powertrains, the U760E delivers ultra-smooth shifts with a response time of ≤220ms — 12% faster than the U660E. Its optimized 6-speed gear ratios (1st 3.350, 2nd 1.950, 3rd 1.320, 4th 1.000, 5th 0.720, 6th 0.600) balance low-end torque for urban driving and high-end overdrive for highway efficiency. For hybrid models, it improves fuel economy by 12-15% compared to the U660E, reducing engine RPM by 350-450 at 120 km/h and minimizing energy loss during electric-gasoline mode transitions.
5. Cost-Effective with Hybrid-Friendly Maintenance
As a mature hybrid-compatible transmission, the U760E offers competitive pricing — 25-30% lower than newer 8-speed hybrid transmissions. Its modular design allows independent replacement of hybrid-specific components (hybrid clutch packs, electronic control modules) and conventional parts (solenoids, valve bodies) without full disassembly, cutting maintenance labor time by 45%. It is compatible with Toyota’s ATF WS and hybrid-specific ATF HP fluids, and replacement parts are widely available globally, reducing downtime for repair shops.
6. All-Climate & Hybrid-Environment Reliability
The U760E operates reliably in a temperature range of -45°C to 150°C, adapting to extreme climates and hybrid system heat loads. Its sealing system uses quadruple-lip Viton rubber seals and titanium-plated gaskets to prevent fluid leakage in high-humidity or corrosive environments. The TCU integrates hybrid-specific monitoring (battery SOC, motor temperature) to adjust shift logic for cold starts, high-temperature hybrid operation, and high-altitude driving, ensuring stability across diverse conditions.
